Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component production, in particular to a film strip laying device. Background Art

[0002] The gap film laminating equipment is used to lay multiple film strips on any one of the protective plates on both sides of the photovoltaic module and on the end faces facing multiple battery strings in a preset arrangement to ensure the effect of gap filling in the subsequent packaging process, wherein the protective plate refers to the photovoltaic glass or backboard in the photovoltaic module. In particular, when laying the film strips on the backboard, the film strips can be reflective film strips, non-transparent EVA film strips, etc., which is conducive to the effective use of sunlight.

[0003] In related technologies, such as Figure 4 As shown, a film strip is laid on any one of the protective plates on both sides of the photovoltaic module and on the end faces facing multiple battery string groups through the film spacing film laminating equipment to ensure the effect of gap filling in the subsequent packaging process, wherein the protective plate refers to the photovoltaic glass or backboard in the photovoltaic module. In particular, when the film strip is laid on the backboard, the film strip can be a reflective film strip, a non-transparent EVA film strip, etc., which is conducive to the effective use of sunlight.

[0004] Among them, the gap film laminating equipment completes the film strip laying on the protective plate through multiple sets of film laminating mechanisms. The film laminating mechanisms include a pressing roller, a film strip roll conveyor, a hot air blower and a cutting assembly. The film strip output by the film strip roll conveyor is pressed onto the protective plate by the pressing roller. The hot air blower heats the part after the starting section of the film strip to make it sticky. The pressing roller rolls on the protective plate to press the heated film strip to bond it to the protective plate. When the above structure is in use, the protective plate is easily crushed by a pressing roller made of too hard a material, while a pressing roller made of a softer material is easily worn and deformed due to continuous heat during rolling. The wear of the pressing surface of the pressing roller will cause the pressing force on the film strip to deviate, which will lead to uneven laying of the film strip. Utility Model Content
